2009年10月11日 · A DHT is a hash table that partitions the keyspace and distributes the parts across a set of nodes. For any new content added to the network, a hash (k) is calculated and a message is sent to any node participating in the DHT. This message is forwarded from node to node until it reaches the node responsible for k.
Taiwan — a 30-year old democracy that just went through its 3rd change of power by election this May — is on the way to creating a something new under the sun.
2020年7月19日 · Card games, poker rounds, games of chance, bets, sports such as football, board games such as Monopoly, races, marathons, puzzles, Tetris, Rubik's Cube, Scrabble, sudoku, online games such as World of Warcraft, and Halo -- all are finite games. The game ends when someone wins. An infinite game, on the other hand, is played to keep the game going.

"In P2P search (a.k.a. distributed search), each individual connected to the network serves its local index as a source of search. Instead of having a central company and a central server, each participant of the network is a search repository. Since we are talking about web indexing and web searching, a user's internet cache might be their contrib...
"A P2P application is different from the traditional client/server model because it acts both as a client and a server. That is to say, while they are able to request information from other servers, they also have the ability to respond to requests for information from other clients, at the same time. Figure 1 shows the architecture of a P2P networ...
"A typical peer-to-peer application has the following key features: • Peer discovery. The application must be able to find other applications that are willing to share information. Historically, the application finds these peers by registering to a central server that maintains a list of all applications currently willing to share, and giving that ...

URL = http://www.mpi-inf.mpg.de/departments/d5/software/minerva/index.html ""Each peer is considered autonomous and has its own local search engine with a crawler and a corresponding local index. Peers share their local indexes (or specific fragments of local indexes) by posting meta-information into the P2P network. This meta-information contains compact statistics and quality-of-service information, and effectively forms a global directory. However, this directory is implemented in a comple...

2008年3月2日 · Description. "OpenFlix provides a directory of movies commonly thought to be in the public domain and works their owners are willing to let be distributed. Public Domain refers to the body of creative works and knowledge in which no person, government or organization has any proprietary interest such as a copyright. These works are considered ...
Description. "Pastry is a generic, scalable and efficient substrate for peer-to-peer applications. Pastry nodes form a decentralized, self-organizing and fault-tolerant overlay network within the Internet. Pastry provides efficient request routing, deterministic object location, and load balancing in an application-independent manner.
Chord is completely decentralized and symmetric, and can find data using only log (N) messages, where N is the number of nodes in the system. Chord's lookup mechanism is provably robust in the face of frequent node failures and re-joins. On top of Chord's routing layer, we have built the DHash block storage system.
